进口高压聚乙烯(英WJG-11)和上海石化总厂塑料厂生产的型号为D025的高压聚乙烯作为电缆绝缘料,具有优良的电气、机械和加工性能,经挤出加工后,挤出线表面光滑、有光泽、透明度较高。但兰州化工厂试生产的牌号为03的高压聚乙烯电缆料,由于聚合方法与前两种料不同,引起高聚物分子结构不相同,而且兰化科分子量分布范围较窄,虽熔融指数与D025料
Imports of high-pressure polyethylene (British WJG-11) and Shanghai Petrochemical Plant Plastic Factory model D025 high-pressure polyethylene as a cable insulation material, with excellent electrical, mechanical and processing properties, the extrusion process, the extrusion line Smooth surface, shiny, high transparency. However, Lanzhou Chemical Plant trial production of grade 03 high pressure polyethylene cable material, as the polymerization method with the first two different materials, causing the polymer molecular structure is not the same, and Orchidaceae molecular weight distribution range is narrow, although the melt index and D025 material
